PRODUCT OVERVIEW
S3C8-SERIES MICROCONTROLLERS
Samsungs S3C8 series of 8-bit single-chip CMOS microcontrollers offers a fast and efficient CPU, a wide range of integrated peripherals, and various mask-programmable ROM sizes. Among the major CPU features are:

   — Efficient register-oriented architecture
   — Selectable CPU clock sources
   — Idle and Stop power-down mode release by interrupt
   — Built-in basic timer with watchdog function
  
A sophisticated interrupt structure recognizes up to eight interrupt levels. Each level can have one or more interrupt sources and vectors. Fast interrupt processing (within a minimum of four CPU clocks) can be assigned to specific interrupt levels.

S3C830A MICROCONTROLLER
The S3C830A single-chip microcontroller are fabricated using the highly advanced CMOS process. Its design is based on the powerful SAM88RC CPU core. Stop and idle (power-down) modes were implemented to reduce power consumption.
The S3C830A is a microcontroller with a 48K-byte mask-programmable ROM embedded.
The S3P830A is a microcontroller with a 48K-byte one-time-programmable ROM embedded.
Using the SAM88RC modular design approach, the following peripherals were integrated with the SAM88RC CPU core:
   — Large number of programable I/O ports (Total 72 pins)
   — PLL frequency synthesizer
   — 16-bits intermediate frequency counter
   — Two synchronous SIO modules
   — Two 8-bit timer/counters
   — One 16-bit timer/counter
   — Low voltage reset
   — A/D converter with 4 selectable input pins
  
OTP
The S3C830A microcontroller is also available in OTP (One Time Programmable) version, S3P830A.
The S3P830A microcontroller has an on-chip 48K-byte one-time-programmable EPROM instead of masked ROM. The S3P830A is comparable to S3C830A, both in function and in pin configuration.
